Description
Technical field
The invention belongs to a kind of mobile communication system higher-layer protocols optimizes between multimode user terminal (being called for short UE) pattern and redirect
(redirection) method of process, relates to shortening the method for redirection process time delay between multimode user terminal pattern.
Background technology
In mobile communication system, along with fast development and the evolution of technology, Multi net voting technology long-term co-existence has been undisputable fact,
Multimode user terminal have also been obtained extensively application and popularizes.For current multiple network technologies, respectively have superiority, such as: 2G mould
The formula network coverage is high, circuit domain business (CS business) is stable；Packet switch domain service (PS business) speed of 4G pattern high but
Coverage rate is relatively low；3G pattern is the most therebetween.Therefore, in the case of current Multi net voting technology alternate covering, many
When mould user terminal performs different business, between network can be according to factor triggering systems such as type of service, power system capacity, signal qualitys
Conversion (such as switching, redirection etc.).
Higher-layer protocols includes Access Layer (Access Stratum, AS) and Non-Access Stratum (Non-Access Stratum, NAS),
Wherein, the wireless heterogeneous networks module (being called for short RRC) of Access Layer is responsible for RRM.Generally, according to UE and network
Between whether there is RRC and connect (under 2G pattern corresponding be that RR connects) UE is divided into idle mode and connected mode.?
Under idle pulley, not having RRC to connect between UE and network, UE only receives downlink network message.When service execution by user,
UE initiates connection establishment request, when after the success of RRC connection establishment, UE enters connection mode.At the end of customer service, network
Initiating Connection Release, UE returns to idle pulley after completing Connection Release.
Between pattern, redirection process refers to that, when the connection mode lower network of a mould initiates Connection Release, network requirement UE discharges
The most resident after connection connecting to another pattern (speech under such as 4G pattern falls process, CSFB process after rise), i.e. network
Release message is configured with the parameter information of redirection target pattern, relates to the rrc of channel release, 3G/4G of 2G
Connection release message.
Describing according to 3GPP related protocol, when network requirement UE is redirected to other patterns, UE should the most resident refer to network
Fixed frequency or community, if resident failure, continuation is attempted resident, if still cannot look on other communities of designated mode
To when meeting resident community, then return original mode of operation (referred to as proterotype) and attempt resident, the idiographic flow of Current protocols
As follows:
1., when multimode UE being under connection mode initiates new business, network is believed according to customer service request, power system capacity etc.
When breath judgement needs UE to be redirected to other patterns, the connection that network carries redirection parameter to the transmission of multimode UE is released
Put message.
2. the Access Layer (being designated as AS1) of multimode UE current operation mode receives the connection release message of network and (wherein carries
The redirection redirection parameter of other patterns) after, preserve message content, perform Connection Release process, then
Request target pattern performs redirection process, i.e. sends to the AS (being designated as AS2) of target pattern and redirects request letter
Number (comprising frequency/cell information that network configures in release message).
3. the AS2 of target pattern receives redirection request, after completing redirection process (namely performing cell selection procedure),
Send to the AS1 of proterotype and redirect confirmation signal, indicate redirection process success or failure.Specifically include:
1) according to parameter information, first frequency/the community of the redirection list of network configuration is carried out signal quality measured；
2) after receiving measurement result, measured value is sorted, by signal quality from strong to weak order, receive the system of each community
Message, if decoding failure or community are unsatisfactory for resident condition, attempts next community the most successively.If at these
Community is found the community meeting resident condition, the most resident on this community, terminate cell selection procedure, simultaneously
AS2 sends to the AS1 of proterotype and redirects confirmation signal, instruction redirection process success, enters step 4；As
Really these communities all resident can not then enter step 3)；
3) AS2 initiates the blind cell selection procedure searched, and attempts other communities resident in this mode；
4) after under target pattern, the blind cell selection procedure searched completes, (whether chosen successfully community is means that redirection process success
Whether), AS2 sends to AS1 and redirects confirmation signal, and instruction redirection process result (select by JiAS2Xia community
The result selected)；
4., after receiving confirmation signal, the AS1 of proterotype redirects result to NAS instruction, performs not according to Different Results simultaneously
Same handling process, redirection process terminates.
Between pattern in the prior art of redirection process, when UE finds persistent district under target pattern, if network configuration
Frequency or community be all unsatisfactory for resident condition, UE then performs the blind cell selection procedure searched under target pattern, it is intended to find it
He can be resident community, this process is that the frequency in the frequency range to supports all under target pattern detects.It is time-consuming longer,
And power consumption is bigger.
Summary of the invention
In consideration of it, the present invention proposes a kind of method optimizing multimode UE redirection process, namely shorten UE under target pattern
Community selects the method for time delay.The concrete scheme flow process of the inventive method is as follows:
S1., when multimode UE being under connection mode initiates new business, network is believed according to customer service request, power system capacity etc.

Ask target pattern to perform redirection process, i.e. send to the AS (being designated as AS2) of target pattern and redirect request signal
(comprising the adjacent cell list preserved under the frequency/cell information and proterotype that network configures in release message).
S4. the AS2 of target pattern receives redirection request, after completing redirection process (namely performing cell selection procedure),
Send to the AS1 of proterotype and redirect confirmation signal, indicate redirection process success or failure.
S41. according to parameter information, first frequency/the community in redirection list is carried out signal quality measured；
S42. after receiving measurement result, measured value is sorted, by signal quality from strong to weak order, receive the system of each community
Message, if decoding failure or community are unsatisfactory for resident condition, attempts next community the most successively.If at these
Community is found the community meeting resident condition, the most resident on this community, terminate cell selection procedure, simultaneously AS2
Send to the AS1 of proterotype and redirect confirmation signal, instruction redirection process success, enter step S5；If
These communities all resident can not then enter step S43；
S43.AS2 initiates the blind cell selection procedure searched, and attempts other communities resident in this mode: measure all band supports
On community, first select unsuccessfully from measuring cell list is deleted in previous step S42 after receiving measurement result
Community, forms new cell list (the most failed community is no longer attempt to), and according to signal quality from strong to weak to little
District sorts, and attempts successively finding the community meeting resident condition；
If S44. finding community (the blindest community searched is chosen successfully) that can be resident under target pattern, AS2 is to proterotype
AS1 send and redirect successful confirmation signal；Otherwise, AS2 sends to AS1 and redirects failed confirmation signal；
S5., after receiving confirmation signal, the AS1 of proterotype redirects result to NAS instruction, performs not according to Different Results simultaneously
Same handling process, redirection process terminates.
In accompanying drawing 1, after UE release connects, the redirection information that the AS1 of proterotype directly configures network in release message
It is sent to target pattern AS2；When these frequency/communities are all unsatisfactory for resident condition, AS2 performs blind searching to the frequency of all supports
Cell selection procedure.
In accompanying drawing 2, after UE release connects, the adjacent cell of the target pattern preserved under this pattern is added in redirection list,
Send, to AS2, the request of redirection after forming new redirection list；If these communities all can not be resident, follow-up AS2 initiates blind
